twill weave

Primitive loom is been used by indigenous peoples of America to weave wool and cotton, even before the arrival of the Spaniards.

A twill weave requires three or more harnesses, depending on its complexity. A twill weave is the second most basic weave that can be made on a fairly simple loom, is made of perpendicular threads going over and under each other always at right angles to each other, creating a very structured fabric. Twill fabrics technically have a front and a back side, unlike plain weave, whose two sides are the same. The front side of the twill is the technical face; the back is called the technical back.

However, woven fabric is made on a loom where the warp (vertical) threads are held in place and the weft (horizontal) thread moves over and under a set number of warp threads to create the desired type of weave.

The highly structure due to the rigid, right angles, nature of wovens make it harder for the individual yarns to rub against each other. Typically woven fabric is more structured and therefore more formal, twills and some other types of weaves may appear to be diagonal, but that’s just an optical illusion. Examples of twill fabric are denim, tweed, chino, gabardine, drill, covert, and serge.
